Abstract

Selon l'invention, on empêche la survenue d'erreurs de parité au niveau de récepteurs de données dans un système de distribution de données au sein duquel plusieurs dispositifs de distribution de données se partagent un chemin de transmission de données. Le système de distribution de données comporte un réseau formé d'un chemin de commande et d'un chemin de données; un contrôleur qui donne des instructions de distribution de données par le biais du chemin de contrôle; au moins un dispositif conçu pour distribuer des données à n'importe quel chemin logique au sein du chemin de données, en fonction des instructions reçues du contrôleur; et un récepteur de données relié de manière fixe au chemin logique concerné au sein du chemin de données. Le contrôleur comprend notamment une section de décision destinée à déterminer une période d'absence de données de distribution sur le chemin logique relié au récepteur de données et à donner, à l'un des dispositifs de distribution de données, les instructions pour distribuer des données fictives pendant ladite période. Le dispositif de distribution de données comprend notamment une section conçue pour distribuer des données fictives munies d'informations de parité appropriées sur la base des instructions.
